The logs look thus: Connecting to MPLAB ICD 2 ....Connected Setting Vdd source to MPLAB ICD 2 Target Device PIC18F452 found, revision =3D c0 ....Reading ICD Product ID Running ICD Self Test ....Passed MPLAB ICD 2 ready for next operation Erasing Target Device... ....Erase Succeeded MPLAB ICD 2 ready for next operation Blank Checking... ....Program Memory ...
